Abstract

The cleaning system for a bundle of tubular filters, open at one end, has injectors (6) facing the filter openings to deliver bursts of compressed air into them. The compressed air supply is controlled by valves (14) into jet tubes (10-12) fitted with the injectors in rows. Only a section of each jet tube is connected to its valve, leading to a U-shaped deflection (20,21a,21b) into a second section in the reverse direction with a closed end (22).

Description

Die Erfindung betrifft eine Reinigungsvorrichtung für ein Bündel rohrförmiger, an einem Ende offen ausgebildeter Filterelemente, vorzugsweise eines industriellen Staubfilters, mit gegenüber den Öffnungen der Filterelemente angeordneten Injektoren zur Abgabe eines impulsartigen Druckluftstrahls in die Filterelemente, wobei die über Ventile gesteuerte Druckluftvorsorgung der Injektoren über mehrere rechtwinklig zu den Injektoren sich erstreckende Düsenrohre erfolgt, und an jedes Düsenrohr in einer Reihe mehrere Injektoren angeschlossen sind.The invention relates to a cleaning device for a bundle of tubular, at one end open trained filter elements, preferably an industrial dust filter, with arranged opposite the openings of the filter elements injectors for delivering a Pulsed compressed air jet into the filter elements, which controlled by valves Compressed air supply of the injectors over several orthogonal to the injectors themselves extending nozzle tubes, and to each nozzle tube in a row a plurality of injectors are connected.

Derartige Reinigungsvorrichtungen finden vorzugsweise bei industriellen Staubfiltern Verwendung, wie sie zum Beispiel aus der DE 44 40 279 A1 bekannt sind. Filterelemente wie z.B. Filterschläuche, Gewebefilter oder Filterrohre sind über die Fläche eines Trennbodens gleichmäßig verteilt, der den Staubluftraum des Filters von dessen Reinluftraum trennt. Die Filterelemente ragen unter ihrem Eigengewicht in den unten angeordneten Staubluftraum, so daß sie von außen nach innen von der staubhaltigen Luft durchströmt werden. An ihrem oberen Ende sind die Filterelemente offen, so daß sie mit dem oberhalb des Trennbodens angeordneten Reinluftraum in Verbindung steht, welcher gegenüber dem Staubluftraum mit einem geringeren Druck betrieben wird.Such cleaning devices are preferably found in industrial dust filters Use, as they are known for example from DE 44 40 279 A1. Filter elements like e.g. Filter hoses, fabric filters or filter tubes are over the surface of a separating tray evenly distributed, which separates the dust air space of the filter from the clean air space. The Filter elements protrude below their own weight in the dust air below, so that they are flowed through from outside to inside of the dusty air. At her upper end, the filter elements are open, so that they are above the separating bottom arranged clean air space is in communication, which with respect to the dust air space with operated at a lower pressure.

Derartige Filterelemente müssen in Abständen gereinigt werden, da sie sich nach einer gewiesen Betriebsdauer von außen her zusetzen. Ein weit verbreitetes Reinigungssystem besteht darin, in Umkehrung der Filtrationsrichtung Druckluft impulsartig von den Öffnungen her in die Filterelemente einzublasen, wodurch der außen haftende Staub bzw. Filterkuchen abplatzen kann, und in eine unterhalb der Filterelemente angeordnete Sammeleinrichtung fällt.Such filter elements must be cleaned at intervals, as they point to one Set operating time from the outside. A widely used cleaning system exists in it, in reversal of the filtration direction compressed air impulsively from the openings ago to blow into the filter elements, whereby the outside adhering dust or filter cake peel off can, and falls into a arranged below the filter elements collecting device.

An die Regeneration der Filterflächen werden dann besonders hohe Anforderungen gestellt, wenn das Filter in Produktionsanlagen mit häufig wechselnden Produkten verwendet wird. Bei einem solchen Einsatz des Filters ist es erforderlich, den gesamten Staubluftraum einschließlich der Filterelemente umfassend zu reinigen, damit bei einem Produktwechsel keine Produktverfälschungen oder Produktverunreinigungen eintreten können. Ein solcher hygienegerechter Betrieb ist vor allem bei der Verarbeitung von Lebensmitteln, pharmazeutischen oder medizinischen Produkten unumgänglich.At the regeneration of the filter surfaces then particularly high demands are made when the filter is used in production plants with frequently changing products. In such use of the filter, it is necessary, the entire dust air space including the filter elements to clean thoroughly, so that at a product change no product falsification or product contamination can occur. Such a Hygienic operation is mainly in the processing of food, pharmaceutical or medical products.

Zur Erzeugung des Druckluftimpulses sind oberhalb der Filterelemente Injektoren angeordnet. In der Regel werden mehrere, in einer Reihe angeordnete Injektoren über ein gemeinsames Düsenrohr mit der für den Reinigungsvorgang erforderlichen Druckluft versorgt. Das als Verteiler dienende Düsenrohr ist über ein schnell schaltbares Ventil mit einem Druckluftspeicher verbindbar. Durch fast schlagartiges Öffnen des Ventils gelangt Druckluft in das Düsenrohr und über die daran angesetzten Injektoren von oben her in die Filterelemente. Der hiermit verbundene steuerungstechnische Aufwand ist relativ hoch, da zwar an das ventilgesteuerte Düsenrohr mehrere Injektoren angeschlossen und damit gleichzeitig betreibbar sind, jedoch jedes Düsenrohr über ein eigenes Ventil an den Druckspeicher angeschlossen werden muß. Die Möglichkeit, sämtliche der in der Regel parallel zueinander verlaufenden Düsenrohre an ein einziges, gemeinsames Ventil anzuschließen und auf diese Weise den steuerungstechnischen Aufwand zu reduzieren, ist eher theoretischer Natur. In der Praxis zeigt sich, daß auf diese Weise keine gleichmäßig verteilte Impulsstärke in allen Injektoren erreichbar ist. Vielmehr besteht die Gefahr, daß einzelne Injektoren mit höherer, und andere Injektoren mit demgegenüber geringerer Impulsstärke arbeiten, was für eine gleichmäßige Abreinigung eines Filters nicht akzeptabel ist.To generate the compressed air pulse injectors are above the filter elements arranged. In general, several, arranged in a row injectors over a common nozzle tube with the required for the cleaning process compressed air provided. The distributor pipe serves as a nozzle with a quick-acting valve a compressed air storage connectable. By almost sudden opening of the valve arrives Compressed air into the nozzle tube and the injectors attached thereto from above into the Filter elements. The associated control engineering effort is relatively high because Although several injectors are connected to the valve-controlled nozzle tube and thus are operable simultaneously, but each nozzle tube via its own valve to the Pressure accumulator must be connected. The possibility of all of them usually To connect parallel nozzle pipes to a single, common valve and to reduce the control effort in this way is more likely theoretical nature. In practice it turns out that in this way no uniformly distributed Pulse strength is achievable in all injectors. Rather, there is a risk that individual Injectors with higher, and other injectors on the other hand, lower pulse strength work, which is unacceptable for uniform cleaning of a filter.

Der Erfindung liegt die Aufgabe zugrunde, eine mit geringem steuerungstechnischen Aufwand arbeitende Reinigungsvorrichtung für ein Bündel rohrförmiger, an einem Ende offen ausgebildeter Filterelemente zu schaffen, wobei die Reinigungsvorrichtung mit gleichmäßig verteilter Impulsstärke der Injektoren arbeiten soll.The invention is based on the object, one with little control technology Effort-consuming cleaning device for a bundle of tubular, open at one end to provide trained filter elements, the cleaning device with evenly distributed impulse strength of the injectors should work.

Zur Lösung dieser Aufgabe wird bei einer Reinigungsvorrichtung mit den eingangs genannten Merkmalen vorgeschlagen, daß nur ein Teil der Düsenrohre unmittelbar an Ventile angeschlossen ist und sich diese Düsenrohre bis zu einer Umlenkung erstrecken, von der aus sich mindestens ein weiteres, an seinem Ende verschlossenes Düsenrohr in umgekehrter Richtung erstreckt.To solve this problem is in a cleaning device with the aforementioned Characteristics proposed that only a part of the nozzle pipes directly to valves is connected and extend these nozzle tubes to a deflection, of the from at least one other, closed at its end nozzle tube in extends in the opposite direction.

Erfindungsgemäß lassen sich daher zumindest zwei Düsenrohrstränge mit einem einzigen Ventil betreiben. Dabei hat sich herausgestellt, daß entgegen der Vermutung, daß die strömungstechnische Umlenkung des Druckluftstroms zu einem spürbaren Druckabfall führt, die Injektoren entlang sowohl des Hinstrangs wie auch des an seinem Ende verschlossenen Rückstrangs mit einer gleichmäßig verteilten Impulsstärke arbeiten.According to the invention, therefore, at least two nozzle tube strands can be combined with a single one Operate valve. It has been found that contrary to the assumption that the fluidic Redirecting the compressed air flow leads to a noticeable pressure drop, the Injectors along both the Hinstrangs as well as the closed at its end Rückstrangs work with a uniformly distributed pulse strength.

Des weiteren hat sich herausgestellt, daß auch bei Weiterbildung der Umlenkung zu einer Verzweigung mit einem Hinstrang und mehreren Rücksträngen keine Nachteile hinsichtlich der angestrebten gleichmäßig verteilten Impulsstärke der Injektoren eintreten. Mit einer besonders vorteilhaften Ausgestaltung der Erfindung wird daher vorgeschlagen, daß die Umlenkung zugleich eine Verzweigung ist, von der aus sich zwei Düsenrohre in umgekehrter Richtung zu dem unmittelbar an das Ventil angeschlossenen Düsenrohr erstrecken.Furthermore, it has been found that even with development of the diversion to a Branching with a Hinstrang and several return strands no disadvantages regarding the desired evenly distributed pulse strength of the injectors occur. With a particularly advantageous embodiment of the invention is therefore proposed that the Deflection at the same time is a branch, from which two nozzle tubes in reverse Direction extend to the directly connected to the valve nozzle tube.

Vorzugsweise ist diese Verzweigung symmetrisch derart, daß sich die sich in umgekehrter Richtung erstreckenden Düsenrohre beiderseits des unmittelbar an das Ventil angeschlossenen Düsenrohres befinden. Bei diesem System von Düsenrohren befindet sich daher der Hinstrang zwischen und vorzugsweise mittig zwischen den Rücksträngen.Preferably, this branch is symmetrical in such a way that in the reverse Direction extending nozzle tubes on both sides of the directly connected to the valve Nozzle tube are located. In this system of nozzle tubes is therefore the Hinstrang between and preferably in the middle between the return strands.

In einer vorteilhaften konstruktiven Ausgestaltung endet das unmittelbar an das Ventil angeschlossene Düsenrohr in einem T-Stück, von dessen beiden Abzweigungen Rohrbögen zu dem Anfang der sich in umgekehrter Richtung erstreckenden Düsenrohre führen, d.h. der Düsenrohre des Rückstrangs.In an advantageous structural embodiment, the directly connected to the valve ends Nozzle tube in a T-piece, from the two branches pipe bends too leading to the beginning of the nozzle tubes extending in the opposite direction, i. of the Nozzle pipes of the Rückstrangs.

Schließlich wird mit einer Ausgestaltung der Reinigungsvorrichtung vorgeschlagen, daß die Querschnitte aller Düsenrohre gleich sind, vorzugsweise auch die Rohrquerschnitte im Bereich der Umlenkung bzw. Verzweigung.Finally, it is proposed with an embodiment of the cleaning device that the Cross sections of all nozzle tubes are the same, preferably also the tube cross sections in the area the deflection or branching.

Die Fig. 1 zeigt ein industriell einsetzbares Staubfilter in einer geschnittenen Gesamtdarstellung. Das Staubfilter besteht aus einem vertikal ausgerichteten, vorzugsweise zylindrischen Filtergehäuse (1), welches durch einen horizontal liegenden Trennboden (2) in einen unten liegenden Staubgasraum (3) und einen oben liegenden Reingasraum (4) unterteilt ist. Der Trennboden (2) ist ähnlich einem Rohrboden gestaltet und verfügt über eine Mehrzahl von Öffnungen für darin eingesetzte, langgestreckte Filterelemente (5). Bei den dargestellten Filterelementen handelt es sich um Filterrohre, die an ihrem unteren Ende bei (5a) verschlossen und an ihrem oberen Ende offen sind. Die Filterelemente (5) sind von oben her in die Öffnungen des Trennbodens (2) eingehängt, wobei sie sich auf der Oberseite des Trennbodens abstützen. Die wirksame Filterfläche wird durch die Mantelfläche der vorzugsweise zylindrisch gestalteten Filterelemente (5) gebildet. Jeweils mehrere Filterelemente (5) des Filterrohrbündels können auch so angeordnet werden, daß sie eine Teilgruppe in Gestalt eines ein Filterpakets bilden.Fig. 1 shows an industrially applicable dust filter in a sectional overall view. The dust filter consists of a vertically oriented, preferably cylindrical Filter housing (1), which by a horizontal separating shelf (2) in a bottom lying dust gas space (3) and an overhead clean gas space (4) is divided. Of the Separation tray (2) is designed similar to a tube sheet and has a plurality of Openings for elongate filter elements (5) inserted therein. In the illustrated filter elements they are filter tubes, which at their lower end at (5a) closed and open at the top. The filter elements (5) are from above suspended in the openings of the partition (2), being on the top of the Support the dividing floor. The effective filter surface is defined by the lateral surface of the preferably formed cylindrical filter elements (5). Several each Filter elements (5) of the filter tube bundle can also be arranged so that they have a Subgroup in the form of a form a filter package.

Über einen Eintritt (8) des Filtergehäuses gelangt das staubhaltige Gas in das Filter. Zum Reinigen und damit Regenerieren der einzelnen Filterelemente (5) des Filterrohrbündels befinden sich oberhalb von deren Öffnungen Injektoren (6) eines Druck-Impuls-Injektorsystems. Kurzzeitig wird über die Injektoren (6) ein starker Luftstrahl von oben her in die Öffnungen der Filterelemente (5) abgegeben, so daß die Filterelemente von dem an deren Außenflächen ausfiltrierten Staub oder dem staubhaltigen Produkt gereinigt werden. Der Staub sammelt sich im unteren Teil des Filtergehäuses (1), weshalb dort ein Staubaustrag (7) angeordnet ist. Das gereinigte Gas tritt bei (9) wieder aus.Via an inlet (8) of the filter housing, the dust-containing gas enters the filter. To the Cleaning and thus regeneration of the individual filter elements (5) of the filter tube bundle located above their openings injectors (6) of a pressure-pulse injector system. For a short time, a strong jet of air is introduced from above into the injectors (6) the openings of the filter elements (5) are discharged, so that the filter elements of the the outer surfaces of which are filtered out dust or the dusty product to be cleaned. The dust collects in the lower part of the filter housing (1), which is why there Dust discharge (7) is arranged. The purified gas exits again at (9).

Die Injektoren (6) befinden sich unten an der Mantelfläche von Düsenrohren (10, 11, 12). In einer einfachsten Ausgestaltung sind hierzu die Düsenrohre (10, 11, 12) mit entsprechenden Öffnungen, d. h. Düsen versehen, welche jeweils exakt auf das darunter angeordnete Filterelement (5) ausgerichtet sind und auf diese Weise als Injektoren dienen. Die Injektoren können aber auch zusätzliche Bauteile sein, die an den Düsenrohren befestigt sind. Auf der Zeichnung ist mit Bezugszeichen (13) ein aus einem Injektor (6) austretender und auf das jeweilige Filterelement gerichteter Druckluftimpuls dargestellt. Über Ventile (14) sind die Düsenrohre (10, 11, 12) mit einem Druckluftspeicher (15) verbindbar. Öffnet das jeweilige Ventil (14), gelangt Druckluft schlagartig über das Düsenrohr zu dessen Injektoren (6).The injectors (6) are located at the bottom of the lateral surface of nozzle tubes (10, 11, 12). In In a simplest embodiment, the nozzle tubes (10, 11, 12) are correspondingly provided for this purpose Openings, d. H. Provided nozzles, each of which exactly to the arranged underneath Filter element (5) are aligned and serve as injectors in this way. The injectors but can also be additional components that are attached to the nozzle tubes. On the Drawing is with reference numeral (13) from an injector (6) emerging and on the respective filter element directed compressed air pulse shown. About valves (14) are the Nozzle tubes (10, 11, 12) with a compressed air reservoir (15) connectable. Opens the respective Valve (14), compressed air arrives abruptly via the nozzle tube to the injectors (6).

Figur 2 läßt als Draufsicht auf das System von Düsenrohren erkennen, daß eine Mehrzahl derartiger Düsenrohre (10, 11, 12) vorhanden sind, wobei diese sich vorzugsweise parallel zueinander erstrecken. Jedes der Düsenrohre (10, 11, 12) weist an seiner Unterseite insgesamt neun Injektoröffnungen auf. Auch die Zahl der Düsenrohre (10, 11, 12) beträgt beim Ausführungsbeispiel neun. Dabei sind die Düsenrohre zu insgesamt drei Gruppen zusammengefaßt. Jede Gruppe wiederum besteht einem mittig angeordneten Düsenrohr (10) sowie zwei zu beiden Seiten angeordneten Düsenrohren (11) und (12). Nur das mittige Düsenrohr ist, wie Fig. 2 ferner erkennen läßt, unmittelbar an das jeweilige Ventil (14) der Gruppe angeschlossen. An seinem anderen, in Fig. 2 linken Ende endet das mittig angeordnete Düsenrohr (10) in einem T-Stück (20). Von der einen Abzweigung des T-Stücks (20) führt ein erster Rohrbogen (21 a) im Viertelkreis zu dem Düsenrohr (11), von der anderen Abzweigung des T-Stücks (20) führt ein zweiter Rohrbogen (21 b) im Viertelkreis zu dem Düsenrohr (12). Das T-Stück (20) sowie die beiden Viertelkreis-Bögen (21 a, 21 b) bilden daher insgesamt eine Strömungsumlenkung mit gleichzeitiger Verzweigung. Vom Ende des mittigen Düsenrohres (10) aus gelangt die Druckluft in die beiden anderen Düsenrohre (11, 12), die sich strömungstechnisch daher in umgekehrter Richtung erstrecken, wie das Düsenrohr (10). Die Druckluft strömt daher, nachdem das Ventil (14) freigegeben wurde, in der einen Richtung entlang des mittigen Düsenrohres (10) und in entgegengesetzter Richtung durch die beiden weiteren Düsenrohre (11, 12). An ihren Enden (22) nahe des Ventils (14) sind die beiden weiteren Düsenrohre (11, 12) verschlossen.Figure 2 can be seen as a plan view of the system of nozzle tubes that a plurality Such nozzle tubes (10, 11, 12) are present, these preferably being parallel extend to each other. Each of the nozzle tubes (10, 11, 12) has a total of at its bottom nine injector openings on. The number of nozzle tubes (10, 11, 12) is at Embodiment nine. The nozzle tubes are a total of three groups summarized. Each group in turn consists of a centrally located nozzle tube (10) and two arranged on both sides of the nozzle tubes (11) and (12). Only the middle one Nozzle tube is, as Fig. 2 further reveals, directly to the respective valve (14) Group connected. At its other, in Fig. 2 left end, the center ends arranged nozzle tube (10) in a T-piece (20). From the one branch of the tee (20) leads a first pipe bend (21 a) in a quarter circle to the nozzle tube (11), of the another branch of the T-piece (20) leads to a second pipe bend (21 b) in the quadrant the nozzle tube (12). The T-piece (20) and the two quadrant arcs (21 a, 21 b) form therefore a total of flow diversion with simultaneous branching. From the end of Centric nozzle tube (10) from the compressed air enters the other two nozzle tubes (11, 12), which therefore flow in the reverse direction, like that Nozzle tube (10). Therefore, the compressed air flows in after the valve (14) has been released the one direction along the central nozzle tube (10) and in opposite Direction through the two other nozzle tubes (11, 12). At their ends (22) near the Valve (14), the two other nozzle tubes (11, 12) are closed.

Die Querschnitte aller Düsenrohre, d.h. sowohl des Düsenrohres (10) des Hinstrangs, wie auch der Düsenrohre (11, 12) des Rückstrangs sind gleich, was die Produktionskosten senkt und insbesondere die Verbindung der Rohre im Bereich des T-Stücks (20) vereinfacht.The cross sections of all nozzle tubes, i. both of the nozzle tube (10) of Hinstrangs how Also, the nozzle tubes (11, 12) of the Rückstrangs are the same, which reduces production costs and in particular the connection of the tubes in the region of the T-piece (20) simplified.

Die drei Ventile (14) lassen sich gemeinsam betätigen oder, was vorteilhafter sein kann, nacheinander. Bei dem dargestellten Ausführungsbeispiel verzweigt sich das unmittelbar an das Ventil (14) angeschlossene Düsenrohr (10) in zwei weitere Düsenrohre (11, 12). Ebenso ist auch eine stärkere Verzweigung möglich, z.B. von einem Düsenrohr des Hinstrangs in insgesamt vier Düsenrohre des Rückstrangs. The three valves (14) can be operated together or, which may be more advantageous successively. In the illustrated embodiment, this branches directly the valve (14) connected nozzle tube (10) in two further nozzle tubes (11, 12). As well also a stronger branching is possible, e.g. from a nozzle pipe of Hinstrangs in a total of four nozzle pipes of the Rückstrangs.
